To use the setDate function from date-fns in JavaScript, first make sure you have installed the date-fns package. You can install it via npm with the following command:

Then, you can import the setDate function into your JavaScript file like this:

2 lines

Once imported, you can use the setDate function to set the date of a given date object. The function takes in two arguments: the date object and the day of the month you want to set it to. Here's an example:

index.tsx
const date = new Date('2021-01-01');
const newDate = setDate(date, 15);

console.log(newDate); // Output: Jan 15 2021

In this example, we created a new date object for January 1, 2021. We then used the setDate function to set the day of the month to 15. The resulting date is January 15, 2021.
